TweetDeck, the enormously popular Twitter client, just got a new redesign across desktop, web, and mobile platforms. As soon as you fire it up, you'll notice that individual tweets are easier to read thanks to better outlining and a stronger font hierarchy. You'll also be able to set your font size in the app's settings (S/M/L). The most drastic change, though, is the Dark/Light button in the top-left corner, which allows you to switch between TweetDeck's traditional black scheme and a new white and teal color scheme. What do you guys think? [TweetDeck]
